A Vietnamese bill of materials can mix protective equipment and ordinary process sensing. The industrial safety and automation catalog is the starting point for that multi-category enquiry; the checks below address the actual purchase rather than treating every sensor as a certified safety device. Compare original-model documentation, commissioning and warranty responsibilities as carefully as the quoted goods price.
What does DAIDISIKE supply for the Vietnam market?
Build the equipment list around the required functions, not a single assumed safety rating. A press opening, robot-cell door, AGV stop function and conveyor position sensor have different evidence requirements. Use safety light-curtain options, LiDAR and scanner categories and safety logic selection to separate them. No common MOQ, response time or certification is established for the whole range.
| Product / Vietnamese term | Model enquiry | Evidence to request | Application boundary |
|---|---|---|---|
| Safety light curtain — màn chắn / rèm an toàn | DQC, DQA, DQT4 and other selected models | Exact certification scope, certified detection capability, protective height and response limits | Assessed press or cell safeguarding; no family-wide Type 4 |
| Scanner / LiDAR — cảm biến laser | ST27 protective-scanner enquiry; DLD / SDLD / DLDS / JPTG ordinary sensing | ST27 confirmed Type 3 / PL d / SIL 2; specific manual and configuration | Non-safety LiDAR cannot substitute for a personnel-protective scanner |
| Safety relay — rơ le an toàn | DA31 exact variant | Input/output compatibility, safety data and supported functions | No assumed EDM, reset, muting, two-hand, timing or terminal assignment |
| Door interlock / guard lock — công tắc / khóa cửa an toàn | Selected DX lock or DX-R1 interlock | Monitoring function versus physical retention; exact force and environmental evidence | A coded interlock alone does not physically lock a guard |
| Proximity sensor — cảm biến tiệm cận | Required M8 / M12 / M18 / M30 configuration | Exact supply, wiring, sensing distance and environment | Ordinary position detection unless separately safety-qualified |
Why buy factory-direct from China instead of a Vietnam reseller?
Direct procurement can simplify communication about configuration and documents, while a local offer may include installation, available spares and warranty handling. Neither route proves identical safety architecture or lower total cost. Compare the exact original and proposed model, certified detection capability, response-time conditions, interfaces and applicable safety data before evaluating the commercial difference.
DAIDISIKE is presented here as a China-based supplier, not a Vietnam office or warehouse. Ask who will perform site installation, stopping-time measurement, safety validation, training and service. Factory photographs, size claims or export-country totals are not substitutes for traceable model evidence and an agreed acceptance plan.
MOQ, lead time, Incoterms and payment for shipping to Vietnam
Put MOQ, production timing, delivery terms and payment in the written offer. Ask for an actual sample quotation, configuration freeze, dispatch estimate and carrier booking. For a Ho Chi Minh City, Hai Phong or Hanoi delivery, separate factory readiness from freight, customs and inland transit. No generic 3–15-day lead or fixed deposit split is guaranteed here.
| Sourcing term | China-direct offer: ask for | Local offer: ask for |
|---|---|---|
| MOQ / sample | Quantity and configuration-specific sample terms | Actual stock or ordering minimum |
| Lead time | Production commitment plus booked route and clearance allowance | Current stock status or confirmed import timing |
| Incoterm / delivery | Version, named place and allocated import responsibilities | Named delivery point and included scope |
| Payment | Accepted instrument and agreed milestones | Quoted currency, credit and acceptance conditions |
| OEM / ODM | Feasibility and whether changes remain within documented safety evidence | Available variants and authorized modification process |
| Customs / conformity documents | Actual invoice, packing, technical and applicable origin/conformity evidence | Traceability and importer documentation for supplied goods |
The comparison columns are questions for both suppliers, not market averages. Name the delivery place and allocate clearance, insurance, taxes and inland delivery. DDP does not bypass licences, accurate declarations or a lawful importer. For any OEM/ODM change, ask whether altered height, detection capability, interface, firmware or connector remains within the applicable certification and manual; a custom label is not approval of a changed safety design.
HS code, import duty and VAT for safety sensors entering Vietnam
Do not select an HS code from the words light curtain or safety scanner alone. Give the broker the exact operating principle, principal function, electrical characteristics, complete assembly/parts presentation and technical literature. Headings such as 9031 and 8536 are comparison questions, not pre-approved codes, and a parts code cannot automatically classify a complete device. Use the Ministry of Industry and Trade tariff search and, where appropriate, the advance-ruling process. The declaration must describe the goods accurately; wording should not be changed to obtain a preferred duty rate.
Confirm the import duty and VAT on the actual classification, customs value and clearance date, including any applicable additional taxes or relief. Resolution 204/2025/QH15 provides an 8% rate for eligible normally-10% groups from 1 July 2025 through 31 December 2026, with exclusions; it is not a blanket sensor rate. For ACFTA, check the official agreement and origin materials, current tariff schedule, consignment rules and claim procedure. Form E supports qualifying origin; a China invoice alone does not prove it or guarantee zero duty. Confirm order-specific proof through the authorized issuing process, not an assumed manufacturer-issued certificate.
Are the products genuine and certified? (Hàng chính hãng & CE)
Authenticity and safety certification are different checks. Match the manufacturer, exact order code and serial identification to the invoice and documentation; verify applicable certificates with the issuing body and obtain the manual for the supplied version. ISO 9001 concerns a quality-management system, not a particular protective function. CE is not a universal Vietnamese import approval or proof that every DAIDISIKE product has the same Type, PL or SIL. Check applicable Vietnamese technical regulations, conformity and import requirements for the actual device with the importer. DQC-family Type 4 or PL e is not established by a family label; DA31 EDM, reset, muting, two-hand, timing and terminal functions are not assumed. ST27 is confirmed Type 3, PL d, SIL 2; DLD, SDLD, DLDS and JPTG are non-safety sensing.
Which installed brands can Vietnamese buyers compare for replacement?
Use the exact installed Autonics, Omron, SICK, Panasonic or Schmersal order code to scope a replacement enquiry. A brand or series name alone does not establish its rating, current availability or compatibility. The table is an evidence-request map, not proof that DAIDISIKE has replaced these products at a Vietnamese customer site or that the alternatives are safety-equivalent.
| Installed brand / series reference | Identify first | Safety-function check | Candidate boundary |
|---|---|---|---|
| Autonics SFLA | Exact order code and manual | Certified detection capability, response and interfaces | Selected curtain only after documented comparison |
| Omron F3SG / F3SJ | Exact model and settings | Rating, protective opening and safety-controller compatibility | No DQC / DQT4 family-wide equivalence |
| SICK C4000 / deTec / microScan3 | Curtain versus protective-scanner role | Exact function and applicable evidence | DLD is not a microScan3 protective replacement; assess ST27 separately |
| Panasonic SF4B | Variant, manual and certificate scope | Mounting, response and restart behavior | DQA / DQC candidate evidence required individually |
| Schmersal switch / curtain | Specific device and actuator | Interlocking, locking or optical function | Do not equate DX-R1 interlock with a physical lock |
| DAIDISIKE configuration | Actual model, accessories and documentation | Complete machine function and required PLr | Quote and validation plan, not automatic equivalence |
The brand replacement and compatibility guide helps organize the comparison. Request original manuals, applicable certificate scope and a circuit-level change review, then recalculate safeguard positioning and validate the machine. Competitor names are nominative only; no partnership, endorsement, current reseller authorization or price advantage is implied.
Two Vietnam application checks: power press & AGV
For máy đột dập, start with stopping capability and access; for AGVs, separate protective sensing from navigation. A curtain cannot contain flying material or make a non-stoppable dangerous stroke safe. Select the required protective arrangement, certified detection capability and height, and position it using total measured stopping time and approach/reach conditions. Both OSSD channels must connect to compatible qualified safety logic controlling validated stopping elements; a normal PLC may receive designated auxiliary status outputs for diagnostics only, never a raw OSSD branch. A rated relay does not automatically achieve the machine's PLr. For AGVs, DLD and SDLD are not alternatives to certified personnel-protective scanners. Consider ST27's confirmed Type 3 / PL d / SIL 2 role only within its documented limits, with field configuration and vehicle stopping behavior validated. Select interlocking versus physical guard-locking devices separately; ordinary proximity sensing is not a substitute for a required protective function.
Send the exact current model, machine and operating modes, required safety function, detection capability, protective height, range, output interface and response constraints. Include quantity, environment, drawings and any custom changes, plus the legal Vietnamese consignee, delivery place and preferred commercial terms. Request a configuration-specific offer and evidence review before scheduling the retrofit.
